Rich chemistry of nitroso compounds

Abstract

Nitrosobenzene or nitrosopyridine are found to be attractive electrophiles in catalytic enantioselective carbon-nitrogen and/or carbon-oxygen bond forming reactions. In the presence of designer Lewis or Brønsted acid catalysts, catalytic enantioselective O- and N-nitroso aldol reaction or nitroso Diels-Alder reaction proceed smoothly. The scope and limitation of new catalytic processes are described.
